Physics: 'Quantum Radio' Breakthrough Could Save Your Life in a Fire, Flood or Earthquake
JAY GORY, MANAGING EDITOR, science
For the first time, physicists have demonstrated that ‘quantum radio’ could function in situations where regular radio signals are no match for high levels of interference—underwater, underground, in remote landscapes or even collapsed buildings. Because the atoms are highly sensitive and respond quickly, the resulting quantum sensors would be able to enhance very low-frequency radio with the best of both worlds—precise signals at an ideal bandwidth. “Our idea was to find a sensor that’s the most sensitive and also still practical that could be used to extend the range,” corresponding author Vladislav Gerginov told Newsweek. read more
